The Process Mineralogy Of Gold: The Classification Of

Abstract. The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold ( 10 m) locked in sulfides.

Carbon In Pulp(cip)is One Of The Methods Of Gold

Apr 30, 2021 Carbon in pulp(CIP)is one of the methods of gold extraction by cyanidation. It is the process of gold cyanide for carbon adsorption after the cyanide leaching of gold-containing materials is completed. In actual production, most CIP plants will encounter various problems, which not only affect the normal operation of gold beneficiation, also seriously damage the economic benefits of CIP.
